adds weight to the argument saying although internal validity and the statistical conclusion adds weight to the causal effect, external validity and construct validity are essential for the causal effects and generalization purposes to many settings. To ensure concrete construct validity level on a study's dependent variable, re-examination for reliability is noteworthy not just the causal effect. Details on the sample and sampling procedures should be analyzed thoroughly for rigorous data Creswell, 2008()
Threats to external validity
Non-representative sampling
It implies a situation where sample picked to act as a representative of the population is insufficient to cover all facets of the population. In this case, the sample is inadequate to act as a representative and is expected to obscure generalization of research result.
Non-representative research context
It describes a situation where the research was set out of context. Example if the survey conducted tried to evaluate the reaction of persons with high intelligence quotient while generalization is subjected to the average person. This question obscures the research results from generalization to a population of persons with an average intelligence quotient.
Threats to construct validity
Inadequate operationalization...
This may occur when populations show wide variations in their responses to particular hypotheses, which are in violation of the expected response. Construct validity may be compromised when alternative correspondences are achieved between a construct and an unexpected concept found within the actual environment being studied. In other words, when the construct does not correspond with the original hypothesis, its validity would be compromised. In cloud computing and determining inside threats,
Validity When conducting a research study, the researcher needs to pay particular attention to the reliability and validity of his or her research instruments. These concepts form the basis of the academic acceptability and even excellence in a study. Hence, any researcher should be concerned with maximizing especially the validity of his or her work. In addition to internal consistency, various forms of validity can be identified, including face validity, content
Validity in Quantitative Research Designs Validity Quantitative Research Designs Validity research refers extent researchers confident effect identify research fact causal relationships. If low validity a study, means research design flawed results . Threats to internal validity in quasi-experimental designs Quasi-experimental studies have several issues that lead to lack of internal validity of the study. These occur as a result of the experimental conditions not being highly controlled or randomized. This leads to intervention
Validity in research is a term that refers to the extent with which researchers are confident that they have determined causal relationships through the cause and effect they identify in their study. As a result, validity is an important aspect of research since it helps in determining whether the research design is flawed and the credibility of research findings. There are various kinds of validity that are utilized in determining
Validity, in essence, has got to do with the extent to which a given research study measures the accuracy of a specific concept – effectively meaning that a study can be said to have passed the validity test if it accurately mirrors that which the researchers set about to investigate. In quantitative research, as Polit and Beck (2012) point out, “researchers strive to design studies that are strong with respect
External Quality Assurance of Assessment Explain the Functions of External Quality Assurance of Assessments in Learning and Development The primary goal for conducting a visit for the purpose of providing a quality assurance assessment of learning and development, it is essential to determine that the learner needs have been identified. The assessor should exit the initial assessment visit with a clear idea of what the learner is expected to know and what
